Abrégé

Despite the eye's immune-privileged status, a secondary loss of vision in some patients treated with AAV led the inventors to question the immunogenicity of AAV vectors after a subretinal injection. The inventors thus characterized anti-transgene and anti-capsid immune responses induced in the periphery after the subretinal AAV injection. Different doses of AAV8 encoding reporter proteins fused with the HY male antigen were injected at day 0 into the subretinal space of adult immunocompetent C57BL/6 female mice. Subretinal AAV injection induced a dose-dependent proinflammatory immune response to the transgene product, correlated with local transgene expression. In order to trigger a subretinal-associated immune inhibition (SRAII) mechanism, some mice were co-injected subretinally at day 0 with AAV and HY peptides. Interestingly, this subretinal co-injection of AAV8 with peptides of the transgene product modulated the anti-transgene T-cell immune response, even at high dose of vector (5.1010 vg). This immunodulation was also confirmed in a pathophysiological murine model of retinal degeneration. The inventors also demonstrated that injection of AAV8 in the subretinal space induces proinflammatory peripheral immune responses to the transgene and the capsid that could be counteracted y co-injection with transgene peptides. Accordingly, the object of the present invention is to provide methods for preventing induction of immune responses to the transgene product and the AAV capsid after ocular gene therapy.

Abrégé

Adeno-associated virus (AAV) is a defective mono-stranded DNA virus, endemic in human population (35-80%). Recurrent clonal AAV2 insertions are associated with the pathogenesis of rare human hepatocellular carcinoma (HCC) developed on normal liver. The aimed of the inventors was to characterize the natural history of AAV infection in the liver. Viral DNA was thus quantified in tumor and non-tumor liver tissues of 1461 patients. Presence of episomal form and viral mRNA expression were analyzed using a DNAse/TaqMan based assay and quantitative RT-PCR. In silico analyses using viral capture data explored viral variants and new clonal insertions. AAV DNA was detected in 21% of the patients equally distributed in 2 major viral subtypes: one similar to AAV2, the other hybrid between AAV2 and AAV13 sequences. Thus the inventors provided an integrated analysis of the wild type AAV infection in the liver with the identification of viral genotypes, molecular forms, helper virus relationship and viral integrations. These findings are important to understand wild type AAV biology and particularly relevant considering the large usage of AAV vector in liver-targeted gene therapy. Thus, the present invention relates to new adeno-associated virus (AAV) variants and uses thereof for gene therapy.

The #β-hemoglobinopathies #β-thalassemia (BT) and sickle cell disease (SCD) are the most frequent genetic disorders worldwide. These diseases are caused by mutations causing reduced or abnormal synthesis of the β-globin chain of the adult hemoglobin (Hb) tetramer. Here, the inventors intend to improve HSC-based gene therapy for β-thalassemia and SCD by developing an innovative, highly infectious LV vector expressing a potent anti-sickling β-globin transgene and a second biological function either increasing fetal γ-globin expression (for β-thalassemia and SCD). More particularly, the inventors have designed a novel lentivirus (LV), which carry two different functions: βAS3 gene addition and gene silencing. This last strategy allows the re-expression of the fetal γ-globin genes (HBG1 and HBG2) and production of the endogenous fetal hemoglobin (HbF). Elevated levels of HbF and HbAS3 (Hb tetramer containing βAS3-globin) will benefit the β-hemoglobinopathy phenotype by increasing the total amount of β-like globin that will: (i) reduce the alpha precipitates and improve the alpha/non alpha ratio in β-thalassemia, and (ii) reduce the sickling in SCD. This combined strategy will improve the β-hemoglobinopathy phenotype at a lower vector copy number (VCN) per cell compared to a LV expressing the βAS3 alone.

IPEX (Immune dysregulation Polyendocrinopathy X linked) syndrome is a primary immunodeficiency caused by mutations in the gene encoding the transcription factor forkhead box P3 (FOXP3), which leads to the loss of function of thymus-derived CD4+CD25+ regulatory T (tTreg) cells. Preclinical and clinical studies suggest that T cell gene therapy approaches designed to selectively restore the repertoire of Treg cells by transfer of wild type FOXP3 gene is a promising potential cure for IPEX. However, there is still a need for a vector that can be used efficiently for the preparation of said Treg cells. The inventors thus compared 6 different lentiviral constructs according to 4 criteria (vector titers, level of transduction of human CD4+ T cells, level of expression of FOXP3 and ΔLNGFR genes, degree of correlation between both expression) and selected one construct comprising a bidirectional PGK-EF1a promoter that showed remarkable efficiency.

Abrégé

Despite the eye's immune-privileged status, a secondary loss of vision in some patients treated with AAV led the inventors to question the immunogenicity of AAV vectors after a subretinal injection. The inventors thus characterized anti-transgene and anti-capsid immune responses induced in the periphery after the subretinal AAV injection. Different doses of AAV8 encoding reporter proteins fused with the HY male antigen were injected at day 0 into the subretinal space of adult immunocompetent C57BL/6 female mice. Subretinal AAV injection induced a dose-dependent proinflammatory immune response to the transgene product, correlated with local transgene expression. In order to trigger a subretinal-associated immune inhibition (SRAII) mechanism, some mice were co-injected subretinally at day 0 with AAV and HY peptides. Interestingly, this subretinal co-injection of AAV8 with peptides of the transgene product modulated the anti-transgene T-cell immune response, even at high dose of vector (5.1010 vg). This immunodulation was also confirmed in a pathophysiological murine model of retinal degeneration. The inventors also demonstrated that injection of AAV8 in the subretinal space induces proinflammatory peripheral immune responses to the transgene and the capsid that could be counteracted by co-injection with transgene peptides. Accordingly, the object of the present invention is to provide methods for preventing induction of immune responses to the transgene product and the AAV capsid after ocular gene therapy.
